To L77 whom t may concern.'

Be 1t lniown that l, CHARLES D. Mc-

'DoNALin a citizen ot the United States, re-

siding at Los Angeles, in the county of Los Angeles and State of California, have `invented new and useful Improvements in Combined Tables, Beds, and Back Rests, o1 which the following is a specilication.

This invention relates to a combined table, bed and back rest, and has for its object to provide a collapsible article which may be readily arranged to assume various forms at will. Another object is to provide a device consisting of a number ot substantial frame elements capable of being` assembled rigidly 'so as to form either' a table frame, a bed trame, or a back rest. Another object is to 'provide a table top adapted'to be readily applied to the erected frame. Another object is to provide a novel construction of supporting means for a mattress and bedding.

Other objects and advantages will be made manifest in the following specification of an embodiment of the invention illustrated in the accompanying drawings, wherein- Figure 1 is a perspective view of the device erected to serve as a table;

Figure Q is a perspective ot' the device arranged to serve as an elongated back rest tor two or more people; i

Figure 3 is a side view or' the device erected so as to serve as an elongated back for the support ot one` individual;

Figure 4 is a cross section through one of the side bars showing the mattress supportin means attached thereto figure 5 is a sectional detail transverselyv along a portion ot the bed straps;

`Figure 6 is aplan and sectional detail otV one ot the corner plates;

Figure 7 is a plan oit a corner-hinge in the frame forming position;

Figure 8 is a plan showing lthe action of the hinge of the trame pieces;

Figure 9 is a side elevation ot one of the legs showing the hook attachment;

Figure 10 is an edge view of a leg showing` the hook guide.

Figure 11 is a sectional view of the table top structure.

The embodiment of the invention here shown includesa suitable number of legs 2, the upper ends of which are hingedly connected at 3 in pairs to respective side rails 4 under andzalang which the several legs 2 Serial N'o. 597,094.

are adapted to be folded, as clearly shown in Figure 2. Then the legs are in the'perpendicular or unfolded position, their ends abut against the contiguous vfaces of the side rails 4. The legs 2 areprovided with elongated loop-like guide wires 5 positioned to receive the hooks 6 of brace wires 7 whose opposite ends are rigidly connected at 8 to to hold t-he legs in erected position; the wire p also holding the legs folded.

Between their top and bottom faces the ends et the side rails 4 are slotted at 11 to receive hinge plates 12 through which pass pivot pins 13 in the ends of the side rails 4. A feature or the invention is that certain ot' the hinge plates 12 are slotted as at'12 toy shift on the pivot pins 13 and thus allow the plates to swing around the endsl of the side rails. The hinge plates 12 are secured by pins 14 to the contiguous end of an end bar 15 forming with the side rails 4 a bed or Ytable frame in the erected position.

At the other ends of the cross bars 15 there are provided plates'12 fastened thereto by pivot pins 14', these plates being provided so that they may be entirely withdrawn from connection with the contiguous ends ot the adjacent side rail 4.

A feature of the invention ,consists of the construction of a mattress supporting means designed to give a desired degree of flexibility. This mattress supporting means is here shown as including a set oi parallel spring rod`s16, one of which is supported along each side rail in a plurality of screw eyes 17 projecting inwardly, the screw eyes beingalternately oiiset along` the respective parallel side rails 4. Extending transverselv from rail to rail is a number of parallel flexible webs or straps, such, for instance.

as woven hemp straps 18, the ends of which are hemmed, and through the'hems extend the spring rods 16. As clearly shown in Figure 2. one end ot each hemp strap 18 straddles one of the rod supporting eyes 17- while the opposite end is spaced between the adjacent pair of supporting eyes, The transverse support formingstraps 18 are thus vieldingly connected to the rails 4 and provide a yielding and comfortable mattress receiving means. Along the underneath of 1hr `actual portions of the straps 18 and along their marginal portions extend flexible straps, as of tape 20, which ,connect the straps 18 and prevent their undue lateral separation.

The structure may be readily converted into a table-like device when it has been erected by the application to the top of the frame ll5 of a table top forming means. rl`his means is shown as comprising a stout sheet of material such, for instance, as canvas. indicated at 21, and longitudinally of the sheetof canvas extend upper and lower slats 22 and 23, respectively, which are shown in Figure l1 as being set in opposed symmetrical relation and fastened through and through, as by rivets 24. The slats 22 and the slats 23 are separated sufficiently at their parallel edges to provide for the rolling of the table top into a small compact form for storage and packing. The unrolled table top device is adapted to be ar- 'anged upon the top of the erected frame, as is clearly shown in Figure l,

The foldable structure is capable of being utilized, as Will be seen from the above description, either as an ordinary bed or cot, when the parts are assembled and braced, or the erected device may be covered by the table top to forni a table. lt is also possible-to use the structure as a comfortable back rest for a number of individuals, this being made possible by folding the corner legsof one of the side rails l up under the rail. as shown in Figure 2, and extendingand bracing the opposite legs and then placing the frame with one yof its side rails don` tow-ard the ground and usingthe fold- V ed out legs as props to support the frame in an inclined position resting on a longitudinal edge, the length of the frame providing` for the comfortable support of a number of individu-als.

in case a single individual should desire to use` the stri'icture as an inclined rest, the corner legs adjacent to one end of the frame are folded in as shown in Figure 3, While tl legs attire other end of the frame are erected and braced and 'then the lower end of the frame can be disposed on the ground or other primary support, the legs at the opposite end oit' the frame holdimithe latter in an upu-*ardly inclined position lengthwise. Attached to the outer faces of the legs 2, which ,fold when erected into the plane of the outer face of respective cross bars l5, are foldable bace and link members 2h, these being pivotally connected as at 26 to respective legs and having at their swinging ends hook portions adapted to be slipped into sockets `27 provided therefor in the outer facesof the cross hars 15. l

My combined table, bed and bag-ck rest kmade having diagonally opposite corners of ner A.. would be of the detachable' kind shown i in Fig. 6, the corner Bof the extensible folding type of Fig. 8, the corner A of the detachable type shown in 6 and the near corner B formed according to Fig. 8 of the extensible type. Therefore, in folding the table or bed the diagonal corners A `and il( Would be disconnected and the end bar 1,5 would be siviv lled outwardly into alinement with its connected side bar et inthe manner illustrated in Fig.` 8, until the end bar and side rail l will bein alinement for the opposite ends of the bed, the legs 2 hav- ,ing been previously folded as above described. Therefore in effect, applicants bed when folded comprises two long bars each the length of the side rails 4;, plus the end bar l5. with the fabric of the bed connecting with bars and which may be utilized te roll them into a neat and compact bundle.

Furthi-ir embodiments, modifications and variations may be resorted to Within the spirit of the invention as here claimed.

That is claimed is:

l. ln a combined table bed and back rest, a pair of side rails, legs pivotally connected to the under face of said side rails, adjacent their ends, adapted to be folded into abutment with the side rails andinto `perpendicularpositions, brace means for holding the legs in perpendicular positions, cross bars connected to the `opposite side rails at the `opposite ends of the bed, said connection comprising a horizontalslot in the side rails, a hinge plate secured to the one end of the cross bars, there being also a vertical pin and slot connection between the hinge plate and the side rail to allow the cross barato hinge .into longitudinal alinement with the side rails, the other` endof each side rail being connected `to the: other end of each cross bar by means of a disconnectible joint.

2. ln a combined table `bed and back rest as claimed in claim l, in which the detachable connection comprises plates secured to the cross bars and attached .to `the side rail by a pair of removable pins.

In testimony whereof I have signed my naine to this specification.
